Hierarchical Energy Sharing Management For A Renewable Energy Community With Heterogeneous End-Users

This paper proposes a new management mechanism for preference-based energy sharing among heterogonous end-users in a centralized renewable energy community. In the proposed hierarchical mechanism, each end-user initially performs a day-ahead self-scheduling based on the internal electricity prices. Then, the community manager optimizes intra-market exchanges in parallel and accomplishes preference-based internal energy sharing to finalize the electricity billing of end-users. Furthermore, by defining value as an intrinsic motivational factor, four types of end-users are introduced in the proposed energy community. According to the prioritized values by the end-users, they are supplied by a mix of different energy classes. Simulation results certify the benefits of the proposed scheme in energy sharing and cost reduction.
